CDCVF25081D is a high-performance clock generator, specifically designed for wide-range communication and computing applications that require highly precise and reliable clock generation. It’s designed to bring flexibility, performance and reliability to system designs, and to create an entire new class of applications.

CDCVF25081D’s application field lies within high-speed communication such as Ethernet, DOCSIS 3.1, FIG.1-4G, 4G/LTE, HDMI2.0, and SONET/SDH networks. Its highest output frequency lies at 800MHz and its input frequency can vary from 8KHZ to 200MHz. It has the capability of seven low phase noise outputs, which support a wide range of applications from extreme clock precision to data conversion and motor drive speed control. It also offers three separate power-on selections, enabling the user to customize it for specific application settings, such as multiple power-up options for data conversion.

CDCVF25081D Working Principle:

CDCVF25081D follows a linear phase-locked loop (PLL) topology. This topology uses a phase frequency detector (PFD), an operational amplifier, an electrically controllable oscillator (ECO) and a high-performance voltage-controlled oscillator (VCO). The PFD measures the frequency and phase difference between the input signal and the feedback signal from the PLL. The output of the PFD is used to control the ECO, which adjusts the operating frequency of the VCO.

The CDCVF25081D can be configured to output clock signals of precise frequency and excellent jitter characteristics. The PLL algorithm of the device incorporates proportional-integral-derivative (PID) control parameters to optimize the system’s performance, as well as an adaptive filtering. Additionally, an embedded automatic-load-current (ALC) tuning circuit helps keep the desired frequency stability during temperature changes. An on-chip PLL loop filter can also be configured to a wide range of corner frequencies.

All of the outputs of CDCVF25081D employ fast settling times, allowing them to switch rapidly between frequencies at a variety of coordination points. This allows the device to be used for applications outside of the traditional communication networks—for example, audio or motor drive speed control. With its fast settling time, this device can also be used as a frequency synthesizer, allowing for the generation of precise output frequencies that may not precisely match the input frequency.

With its unique combination of innovative design and advanced technology, the CDCVF25081D enables system designers to develop products with higher performance and better efficiency than ever before. Additionally, its wide range of clock capabilities ensures that it can be used in a wide variety of applications, and its embedded features provide more flexibility, reliability and efficiency than ever before.
